Instinctive, spontaneous and unclassifiable, Walter Pfeiffer’s images are an anthem to youthfulness, and not only that of the mind. This may explain why, in spite of a monopolizing international success, he accepted ECAL’s invitation to run the 2014/15 Workshop, and enjoyed sharing his experience with the emerging photographers of the Lausanne school. He invited students to take hold of his world without ever imposing a specific goal. Collected under the title 'Choli Cholie' – an allusion to a recurring remark by the artist –, the images produced by the students are at once a reference and a tribute to the work of the famous photographer.
